A Four-Way Switch Wiring Diagram depicting the LINE and the LOAD in two separate switch boxes. A two conductor cable with a grounding conductor supply's power from the source to the first three-way switch. From the first switch a three conductor cable goes to the first four-way switch and then to the next four-way switch and ends at the last three-way switch.
